If they want their platform to expand and be like the next FortuneJack, Roobet, or Sportsbest, then they should have done a good marketing and bitcointalk forum is a really good hub for gambling.
You got it right and they shouldnt stop right there because collaboration stuff wont really work out if there would be no follow-up in terms of marketing.It wont really be effective because people will just forget that they do able to read up such collab then move forward unless if they do make more marketing and should able to utilize the name of Binance as part of it then they might have a chance to be popular but as said that it will also
matter if the site is fair in the first place or does have good ui or overall service because it would all come to waste if they do lack into that thing but to know that Binance do made up some deal then they might
really have those qualities.
using BNB is already a good marketing technique to attract players. now, they have to maximise this opportunity as much as they can. if they will do marketing campaigns/promos with attached BNB logo, I think many users will check them out. but yes, they need to be on top of their game always. as people are expecting high standard of service.
